Question

“In the mountainous regions, mini-hydel plants prove to be cost-effective as well as eco-friendly.”

Justify the above statement with valid arguments.

Answer 1

Mini-hydel plants are small-scale hydroelectric projects that generate electricity using small rivers and streams. They are particularly beneficial in mountainous regions due to the following reasons:

1. Cost-effective Energy Source: Mini-hydel plants require lower capital investment compared to large dams. They utilise natural water flow, reducing the need for large infrastructure and expensive maintenance.
2. Eco-Friendly & Sustainable: These plants do not cause large-scale deforestation or displacement, unlike big hydro projects. They produce clean, renewable energy without emitting harmful greenhouse gases.
3. Efficient for Remote Areas: Mountainous regions often face electricity shortages due to difficult terrain. Mini-hydel plants provide a reliable local power supply for villages and small towns.
4. Minimal Environmental Impact: Unlike large dams, mini-hydel projects do not disrupt natural river ecosystems. They ensure sustainable energy production while preserving biodiversity.

Thus, mini-hydel plants are a practical, cost-efficient, and environmentally friendly solution for power generation in mountainous regions.
